One obvious advantage is that it is new, so you don't have to worry about bad surrounds (ever again), wrongly installed kits, etc.

Compared to a 2235 it is objectively better on excursion (very silent), will have less intermodulation (meaning it will be much better at playing both LF and MF at the same time), and is less subject to power compression thanks to its TCR VC.
Looking at the different white papers, the compression curve of a 4367 appears quite similar to that of a 4435 equipped with *two* 2234. This is quite a feat although it is maybe not a fair comparison given these measurements have been taken decades apart, so conditions might vary...

One thing to consider though is its rising response, which requires a specific passive network or active EQ to handle. The "-1" variant is easier to deal with in this regard.
It is clearly not a drop-in replacement for any of the vintage drivers, which were meant to be flat out of the box (in the box )
